Management of the Sanitation Service Authority (SSA) is once again cautioning Barbadians to refrain from using threatening behaviour towards sanitation workers as they carry out their duties.Public relations officer at the SSA Carl Alff Padmore repeated the plea to Barbados TODAY as he related an incident in the Mangrove St Philip area on Monday, where a resident allegedly acted in a threatening manner when told by SSA workers about they way in which they had handled the dumping of cooking oil, which had splashed them during their duties.Padmore, who also spoke last month about an alleged assault on a worker by a store owner in Bridgetown, said that the rise in incidents of confrontation was deeply worrying.
